摘要：

X-ray diffraction patterns reveal that all samples contain the single Pb2Sr2YCu3O8+y phase. The results of electrical-resistivity measurements show that Pb2Sr2RCu3O8+y (R=Y, Pr, Gd and Tb) are not superconducting at temperatures above 1 0 K. The paramagnetic effective moments mu(eff) and the magnetic transition temperatures T(N) derived from the magnetic susceptibility data are 3.11mu(B), 7.94mu(B) and 10.04mu(B), and 8.5 K, 3 K and 5.5 K for R=Pr-, Gd- and Tb-containing compounds, respectively. The similarities and differences in terms of electrical and magnetic properties of these compounds compared with those of the corresponding RBa2Cu3O7-delta are briefly discussed.
